- describe and utilise Newton's theory of gravity;
- describe the basic mechanical properties of solids and fluids.
- derive and use the transformation equations of special relativity;
- compute the energy and momentum of relativistic particles;
- summarise relativistic systems on a Minkowski spacetime diagram;
- understand the core difference between quantum and classical physics;
- represent quantum systems with two classical states;
- compute measurement probabilities and quantum evolutions;
